Heart defects are associated with the structure of the heart. When any defect appears in the structure of the heart, it disrupts the normal flow of blood through the heart. The blood flow can slow down and sometimes flow in the wrong direction or to the wrong place and blocked completely. Sometimes, many heart defects are present at birth. For instance, congenital heart defect (CHD) is the most common type of birth defect. Some CHDs also cause heart block. Heart block is one of the severe medical conditions that occur with the heart's electrical system. This electrical system controls the rate and rhythm of heartbeats. These types of heart defects require specific heart closure devices for their treatment.

In terms of geographic, North America dominates the global heart closure device market. The U.S. represents the largest market for heart defect closure device followed by Canada in North America. However, Asia is expected to show high growth rates in the next five years in global heart defect closure device market due to increasing aging population. Older people are more susceptible towards heart stroke than adults. This would increase the demand of heart closure devices for their treatment. China and India are expected to be the fastest growing heart defect closure device markets in Asia.

In recent time, rising number of arterial fibrillation patients and increasing incidence of CHDs are some of the major drivers for global heart defect closure device market. Increasing incidence of CHDs and rising number of arterial fibrillation patients have led to the demand heart defect closure devices for their treatment. In addition, advancement in heart closure device technology is also fueling the growth of the global heart defect closure device market. However, stringent regulations and high cost involved in manufacturing of devices are some of the key restraints for global heart defect closure device market. In addition, high risk of complications associated with treatment also hampers the growth of global heart defect closure device market.
